A/HRC/25/49/Add.1 The various levels of government should create an environment conducive to cooperation and working relations among all cultural institutions, without interference from political actors. 104. Reforming the education system to end the segregation of pupils according to national/ethnic affiliation in both the two-schools-under-one-roof system and mononational/ethnic schools is vital and urgent. For this, efforts must be pursued to implement a common core curriculum and to increase the number of subjects in which children learn together, regardless of background, including in those labelled “integrated schools” (where in fact interaction is minimal). The Special Rapporteur recommends that: (a) Steps be taken to increase significantly the number of joint cultural activities between students across communities within two-schools-under-one-roof schools and between mono-national/ethnic schools; (b) The right of all pupils and students to learn in their mother tongue and to have access to the cultural heritage of their particular community as well as those of all others be guaranteed. Children should learn the three official languages of Bosnia and Herzegovina, and both the Cyrillic and Latin alphabets, as necessary tools for full access to their cultural heritage. 105. Neither history nor literature should be manipulated to indoctrinate students into believing in mutually exclusive and antagonistic identities. 106. Efforts should be increased to ensure a comparative and multi-perspective approach in history teaching, to develop a multi-voice narrative that acknowledges different viewpoints, and to promote critical thinking, analytic learning and debate among students.37 The Special Rapporteur recommends that: (a) textbooks; Authorities at all levels pursue their efforts to raise the quality of history (b) A wide array of textbooks by a range of publishers be accredited. The curriculum should allocate a certain amount of time (at least 30 per cent) for teachers to introduce supplementary material, especially primary historical resources, without prior approval by the ministry; (c) Transparent approval and accreditation procedures and criteria for textbook selection be adopted, relying on expertise in history and pedagogy, not particular ideological and political requirements. Those procedures should include, for example, open tenders in which all publishers may bid equally, and independent expert committee reviews to ensure that textbooks meet required standards. (d) Cooperation among researchers of various communities be envisaged and promoted, such as inviting them to review each other’s textbooks for comments. 107. The State and the entities should ensure that children have access to literature offering diverse viewpoints and mutual understanding. 108. Respecting, protecting and promoting academic freedoms across the whole territory of Bosnia and Herzegovina is vital. This includes the freedoms to choose research subjects, to have access to information, including archives, without discrimination, to collaborate and exchange views with others, to disseminate results 37 See A/68/296. 21
